Even if you're well past puberty, your body odor can keep changing and surprising you all throughout adulthood. It's just one of those great benefits of growing up. In fact, the way your body odor changes as you get older can get a bit surprising and strange. That signature scent just continues to evolve over time for most people, it seems.
To be clear, though, some amount of body odor is totally normal and expected. Also known as bromhidrosis, body odor is a totally natural part of being a human, as noted in Very Well Health. Although a person's lifestyle habits and medical history can affect this scent, part of it is just determined by genetics, as further explained in Very Well Health. People aren't meant to be totally scent-free all the time, and some amount of body odor isn't even within your control.
Along those lines, there are some specific ways that body odor can change as a person goes through the aging process. A lot of it is just determined by the natural ways the body reacts to different compounds, hormones, or even minerals, so it's not entirely within an individual's control. So read on to learn about the subtle (and more overt) ways your BO can change over time.
